As Alexis said I and some others asked but it was refused for some
reasons ( i remember to disagree with those reasons but didn't managed
to convince them)

IIRC all the chroma converters in vlc are/were not yet being converter to
swscale so being able to compile with the old version is/was a good

But the issue remains that we needs to compile to be sure to have a
ffmpeg with a real swscale
